ExceptionCondition
ArgumentOutOfRangeException

year is outside the range supported by the calendar.

-or-

month is outside the range supported by the calendar.

-or-

era is outside the range supported by the calendar.

For example, in GregorianCalendar, GetDaysInMonth for February returns 28 in a common year or 29 in a leap year.

Notes to Inheritors

The derived class must support CurrentEra when it is passed as the era parameter. One way to support CurrentEra is by replacing it with the value stored in Eras[0], which is the value for the current era of the calendar.
